[Gimp-docs] xml2po & placeholder errors

[Ulf-D. Ehlert]

Hi,

we have a minor problem with "xml2po" producing those mysterious 
placeholder errors Vitaly reported some times ago ("No template matches 
placeholder-1 ...").

Our problem: we have two slightly different xml2po versions creating 
different po files. So we just have to decide which version to use.

When we started to find out how to create po files, I noticed 
that 'ml2po' sometimes emitted placeholder tags. I considered this to 
be a bug, filed a bugreport and provided a patch - without any response 
from the xml2po maintainer (obviously everywhere the same problem: lack 
of time). You find this patched version in our tools directory, and 
whenever you are using Makefile.GNU you invoke this one.

The autotools-based Makefile uses the default xml2po program shipped 
with the gnome-doc-utils package (on Linux).

A typical output example (default version ("-") vs. patched version 
("+")) shows the difference:

 #: src/menus/colors/auto/color-enhance.xml:58(phrase)
-msgid "<placeholder-1/> example"
+msgid "<quote>Color Enhance</quote> example"
 msgstr ""

 #: src/menus/colors/auto/color-enhance.xml:62(phrase)
-msgid "<placeholder-1/> example (Original image)"
+msgid "<quote>Color Enhance</quote> example (Original image)"
 msgstr ""


(I still think this is a bug, since it may easily lead to translation 
errors if you don't look at the context.)

Obviously we can't continue using both versions...

Using the patched version would be a kind of fork with all its 
implications: maintenance, updating, bugfixes etc. (but note it's just 
a little Python script...). There are also some advantages: we could 
customize the program and add more patches (for instance, we could try 
to make xml2po's images-md5 feature work for us).

Ok, that's all, just make your choice and then we will have to stick 
with whatever you have chosen.

Unless we stumble across another bug/problem, both solutions should be 
fine...

Bye,
Ulf
